4.4 Connection Variants
This chapter describes the proper wiring of the module in safety-related applications. The
connection variants specified here are permitted.
The inputs and outputs are wired via connector boards. Special connector boards are available
for redundantly wiring the modules, see Chapter 3.6.
The supply is decoupled using diodes. This ensures that the supplies of two modules can
supply one proximity switch if the modules are redundant to one another
Additionally, a HART handheld can be configured for evaluation
or set-up purposes; this HART
handheld operates as secondary master and is connected in parallel to the transmitter/actuator.
The operator is responsible for ensuring safety
-related and proper configuration of the HART
4.4.1 HART Module with Analog Input Module
Connector boards X-CB 016 01 (with screw terminals) or X-CB 016 03 (with cable plug) can be
used to perform the wiring such as described in Figure 15.
